Android Question [Solved] How to put a Circle (Radius) on Map GoogleMapsExtra?

[JoseTrujillo]

Hi everyone:

My Name is José Trujillo, i'm from Chile...

i have a problem, and i can't solved it, i try to put a circle on "any location for now", with the next code:

'Dim CircleRadio As Circle
Dim MapRadio As CircleOptions
MapRadio.Initialize
MapRadio.Center(vPosicionGPS_ToMQTT)
MapRadio.Radius(1000)
MapRadio.FillColor(0xFFEF9A9A)
'MapRadio.StrokeColor(0xFFE57373)
MapRadio.StrokeColor(0xFFEF5350)
MapRadio.StrokeWidth(10dip)
MapRadio.Visible(True)
GMapsExtra.AddCircle(gmap, MapRadio)

- Object called "gmap" is an instance of Lib GoogleMap (I Can see, move, zoom, pinch in, pinch out, renderize and work with the map and full properties and events correctly)

- This lines are in the end of the event "MapFragment_Ready" after my own code.

- The error on Compile is the next:

B4A version: 5.02 (1)

mostCurrent._gmapsextra.AddCircle((com.google.android.gms.maps.GoogleMap)(mostCurrent._gmap.getObject()),(com.google.android.gms.maps.model.CircleOptions)(_mapradio.getObject()));
^
symbol: class CircleOptions
location: package com.google.android.gms.maps.model


- Someone know why this happens? i search in all this forum about any tutorial of GoogleMapsExtras and there is no example for implement this.

thank you very much!!!

have you tried:

MapRadio.StrokeColor=Colors.ARGB( 150,255,255,0)

Erel, Thanks! but my problem it was not that, my problem was the Version of Library "jar" of GoogleMaps, an his "resources folder"

The Version with the problem is:

'GOOGLE MAPS - v2.0.12
'#AdditionalJar: google-play-services_OLD
'#AdditionalRes: "E:/B4AResources/google_play_services/libproject/google-play-services_lib/res", com.google.android.gms
'#AdditionalRes: ../resources/google_play_services/libproject/google-play-services_lib/res", com.google.android.gms

i Updated to a new version on my project, the next:

'GOOGLE MAPS - v6.5.87
#AdditionalJar: google-play-services
#AdditionalRes: ../resources/google_play_services_new/res, com.google.android.gms

This version i found in this folder on my Android SDK, into the next file "play-services-6.5.87.aar":

- android-sdk\extras\google\m2repository\com\google\android\gms\play-services\6.5.87\play-services-6.5.87.aar

this file i opened with WinRar (or similar) and extract it on my project resource folder, now, the map renderization it has been updated with new interface and look & feel, the renderization is faster and High Quality!!!

very good and thank you very much, becouse i try your code and not work for my. this give me the begin for solve and update the quality of the Application

thanks!

PD: Sorry for my english if something is wrong

The correct solution is to upgrade to B4A v6 and use the new maven repositories.
